Abstract

A base station device (31) provided in a unit cell (41) is included in a base station controller (21), and a base station device (32) provided in a unit cell (42) is included in a base station controller (22). A base station device (33) provided in a boundary cell (43) adjacent to both the unit cell (41) and the unit cell (42) is included in the base station controller (21) and the base station controller (22). Frequencies (RF#1, RF#2) are allocated to the unit cell (41), the unit cell (42) and the boundary cell (43), respectively. The communications associated with the base station device (33) at the frequency (RF#1) are controlled by the base station controller (21) while those at the frequency (RF#2) are controlled by the base station controller (22).
